Removwithin hody @tion o T in the upper surface of the bloc-k, and oonstitutes en electrical connection between the Contact 4 and the Contact 6. The free end of the resi. Ient contact 6 is offset in an upward direction, with respect to the end, thereof which is engaged by the bolt 5, to en extent such that it will. project to the eenter and extend above the .upper surface of the block 3, as shown in Figure 3. Mounted 'ithin the chamber of the block 3 is an aroshaped spring conteot 8 having an upwardly extending 9 at one end thereof engaging Within recetas 1G formed in the upper Wall of the bloeit 'whereby the spring contant is held .fig-einst nodi movement. The fr end of the spring Contact 8 isv in regist r with .and normally spaced from the Contact 4, but is adapted to be moved into engagement withv the Contact by ineens of a. push button. ll projecting through an opening l2 oi the casing, the side Wall of the block 3 coing out sway indicated at 13 to receive inner end of the ush button which eng' C, :u the free end ot the spring contact 8. Arjeccnt its inner end the push button is provided with e funge 14 to iiniit the outward movement thereof. The upper portion of the block E is reduced slightly, as shown in Figure 37 nd upon this reduced portion is mounted an annular enged eontact member Positioned within the casing above the 'block is e heating unit comprising L dise lo formed of a suitable insulating material adapted to withstand a high heut, such as lave, or the like, and having a, spiral groove l? formed in its upper surface within which is received :i coiled wire 18 'formed of e noneorrfcrsive material which offers a` high resistance te the message of en electrie current therethrin One end of the wire 18 passes do'wnwai through a. hole 19 in the center of the dise l@ unil is secured to a, metal terininul inenbf i() in any suitable manner, as for example by nie-ens of solrler. The other end Yof the Wire i8 extends downwardly rough u. bei@ 2i adjacent the periphery of and is lient outwardly to pass meh 22 formed in the lower snre oi the dise. whereby the outwardly-ex l-endin i free end of the Wire is held aga-inst mi nov i The notch 22 is prefer- ,slightly less than the dii8 to insure that the Wire the annular contapt 15 gege with,

when the parts are assembled as hereinafter described. lu order to insure that the coiled `Wire 18 will be positively held within the groove 17- it is preferably anchored or tied in position at"a plurality oit points throughout its lengtln as indicated at 23, Fig. 2. The

anchoring means each comprises a piece of Wire or the like 24e folded upon itself at the central portion thereofl and extending downwardly through a' hole 25 formed in the disc 16,-the bent portion ot' the Wire straddlingr the Wire 18 and holding it firmly seated within ,the groovel?, as shown in Fig. 3. The anchoring wire 24 is locked in position by having its free ends nent outwardly in opposite directions as indicated in Figures 3 and 5. The lower .irt'ace of the disc 16 is preferably provided lWith recesses 26 to receivel the bent ends of the anchoring wires 24 in order to protect them and to insure that they will not engage either or the contacts carried by the block 3.

When the heating` unit is in position above the block 3, the centrally positioned terminal member 20, to which one end of the resistance Wire 18 is secured, engages the free end of the resilient contact 6, and the other end ot wire 18, which extends outwardly from the disc 16, engages the annular contact 15. The heating unit is held in position by lthe annular cap 2, the inner portion of which is sloped to engage the periphery ot the disc 16 and the outer edge of the upper surface thereof, as shown in Fig. 3. rlhe cap 2 thus serves to center the disc with respect to the block 3, and as the cap is screwed into position upon the body portion 1 of the casing, the heating unit is drawn downwardly, thus insuring that the terminals ot' the resistance Wire 18 will be pressedinto engagement with the contacts and 15. lt is pointed out that there is no interlockingengagement hetvveen the heatingunit and the block 3, which would necessitate the heating` unit beingpositioned in a certain definite relation with respect to the block. and that Whatever the position of the heating 'unit with respect to the block may be, the central terminal member 20 will engage the resilient contact 6 and the outer ond of 'the Wi 1e 18 will engage .the annularcontact l5. rlhe device is connected .to a suitable source of current, not shown, loyl the conductors 2? which are led into the casing through an opening 28 formed in the rear Wall of the body portion 1. One of the conductors is connected to the spring contact 8, preferably adjacent the fixed end thereof, in lany suitable manner as, for example, by means or' a solder, and the other of the condoctors passes through a hole 29 formed in the upper portion of the block' 3 and is secured to the annular Contact 15" in any suit able manner. [is the 'free end of the spring contact -8 is normally out ot engagement with the. root-act 4. no current can l flow through the device.

i ,1i-sence When it is desired to utilize the device tor lighting a cigar or the like, it is merely necessary to press upoY push button 11 to cause the tree end o spring contact 8 to engage the conta' whereupon current will flow from one or conductors 27 through spring Contact l?, r tact fr, bolt 5, resilient contact G, resista Wire 18, annular contact 15, to the other conductor 27. The resistance wirr-:18 will thereupon become heated to a dirree cient to permita cigar or the e to be lighted therefrom in the 'usual manner. Should the heating unit become unfit For use. for any reason, it is merely necessary to uA screw the cap 2, remove the heatingl una', put a new heating unit in position', and then screw the cap in position upon the body portion of the casing. As it is not necessary 'to unfasten the terminals of the damaged heating unit from contact members Within the casing and to attach thereto the terminals of the nen7 heating unit, the replacing ot the damaged unit by a new unit may be accomplished in the minimum length ot', time, and on il'urthermore the change of units m12 he et tected by unskilled persons Without danger of causing short circuits between the current conrhicting` parts of the device.

lt is also pointed out that all or' the our rent conducting parts of the device so arranged that they cannot come into contact with the metal casing, thus insuringr that the device ma be handled with per'tect safety.

lll/hilo have 'illustrated and described my invention in connection with a preferred ein bodiment thereof, it will be 'understood that l do not intend to limit myselt' to the specific embodiment shown, but that ll intend to cover my invention broadly in whatever tot torni its principle may be employed.
